kinds: also define the possibly qualified symbol kinds

Browse Source 
* data/skeletons/bison.m4 (b4_symbol_kind): Rename as...
(b4_symbol_kind_base): this.
(b4_symbol_kind): New, for fully qualified kind name.
* data/skeletons/lalr1.cc (b4_symbol_kind): New.
Adjust to use b4_symbol_kind where appropriate.
* src/parse-gram.h, src/parse-gram.c: regen.

The macro `b4_symbol(NUM, FIELD)` gives access to the following FIELDS:
- `has_id`: 0 or 1
Whether the symbol has an id.
Whether the symbol has an `id`.
- `id`: string
If has_id, the id (prefixed by api.token.prefix if defined), otherwise
defined as empty. Guaranteed to be usable as a C identifier. This is
used to define the token kind (i.e., the enum used by the return value of
yylex).
If `has_id`, the name of the token kind (prefixed by api.token.prefix if
defined), otherwise empty. Guaranteed to be usable as a C identifier.
This is used to define the token kind (i.e., the enum used by the return
value of yylex). Should be named `token_kind`.
- `tag`: string
A human representation of the symbol. Can be 'foo', 'foo.id', '"foo"' etc.
A human readable representation of the symbol. Can be `'foo'`,
`'foo.id'`, `'"foo"'` etc.
- `code`: integer
The token code associated to the `id`.
The token code associated to the token kind `id`.
The external number as used by yylex. Can be ASCII code when a character,
some number chosen by bison, or some user number in the case of `%token
FOO <NUM>`. Corresponds to `yychar` in `yacc.c`.

- `is_token`: 0 or 1
Whether this is a terminal symbol.
- `kind_base`: string
The base of the symbol kind, i.e., the enumerator of this symbol (token or
nonterminal) which is mapping to its `number`.
- `kind`: string
The symbol kind, i.e., the enumerator of this symbol (token or nonterminal)
which is mapping to its `number`.
Same as `kind_base`, but possibly with a prefix in some languages. E.g.,
EOF's `kind_base` and `kind` are `YYSYMBOL_YYEOF` in C, but are
`S_YYEMPTY` and `symbol_kind::S_YYEMPTY` in C++.
- `number`: integer
The code associated to the `kind`.
